Tube feet are the many small tubular projections found most famously on the oral face of a sea star's arms, but are characteristic of the water vascular system of the echinoderm phylum which also includes sea urchins, sand dollars and sea cucumbers and many other sea...

The grooves contain rows of tiny, flexible appendages called tube feet. Sea stars move by means of the tube feet, which are operated by a hydraulic, or water-vascular, system unique to echinoderms. Seawater, circulated through the radiating canals of this system, enters and extends the tube feet.

Typically, these are tube feet, pedicellaria, and gills. All echinoderms have a water-vascular system, a set of water-filled canals branching from a ring canal that encircles the gut. ... The canals lead to podia, or tube feet, which are sucker-like appendages that the echinoderm can use to move, grip the substrate,

The radial canals in crinoids run along each arm into an ambulcral groove and tube feet. The ambulacral groove with its many cilia and hydraulically driven tube feet manipulate captured food down the ambulacral grooves along the arms down to the mouth, situated at the tegmen which is positioned at the base of the arms.

Crinoids are suspension feeders, capturing planktonic organisms in a network of mucus produced by soft appendages, called tube feet, contained in grooves on the tentacles, or arms.

Comparative Morphology of Tube Feet Among the Asteroidea: Phylogenetic Implications1 ... This has become an accepted model despite the fact that the comparative morphology of asteroid tube feet has not been considered. In the present study we examine tube-foot morphology of 45 species of Asteroidea representing 19 families.
